Hi, I have a honda lawnmower model HRX217KVKA ser MAGA 1400114 that I am having very low drive output so I replaced the cable and put on a new belt. this did not change performance at all, so i was told that the transmission is bad, i got the new updated one I think part number 06200-vh7-305 it had diferent type of arm that large spring attached to, what looks like a plastic pully... I thought great this will correct my problem but, no I still have no drive. I am able to adjust ca, to lock up wheels with engine off while pushing down on paddles...now I am thinking i should see if the old arm (may also be used as belt tenisioner) should have been put on/changed befor installing new transmission... any help will make my wife happy as she loves to cut the grass..
